They (2002) Timeline Explained – Every Event in Order

Billy killed himself because he was overwhelmed by the creatures that had been terrorizing him since childhood. After being abducted from his closet in 1983 and missing for two days, Billy spent his life believing the creatures would return. When he reunited with Julia in 2002 and warned her about staying out of the dark, he was already at his breaking point. The flickering lights in the diner triggered a panic attack, and rather than be taken by the creatures again, he chose to end his life. His suicide was an attempt to escape the inevitable pursuit rather than face the creatures.

The creatures are supernatural beings that exist in a dark parallel dimension accessible through closets, mirrors, and other dark spaces. They target individuals who experienced night terrors as children, emerging from shadows to drag victims into their realm. The creatures have been abducting people for decades, as shown when Billy was taken in 1983. They appear as dark apparitions and can manifest in the real world when darkness is present. The creatures seem to feed on their victims, with Sarah warning that 'They will eat you' in nightmares.

Foreshadowing: Early in the film, Billy's mother tells him the monster in his closet is imaginary, but the creature emerges anyway, establishing they are very real.

The mark appears on people who have been targeted by the creatures. It manifests as a strange symbol that grows on the skin, Billy had it on his hand, Sam on his shoulder, and Terry on her ankle. When the mark appears, a long black needle emerges from the body, signaling that the person is about to be taken. Julia discovers the mark on her forehead and pulls out the needle, but this does not prevent the creatures from eventually capturing her. The mark serves as both a warning and a portal for the creatures to claim their victims.

The creatures specifically hunt people who experienced night terrors as children. Julia, Billy, Terry, Sam, and Sarah all had severe night terrors triggered by traumatic events, Julia witnessed her father's suicide, Terry saw her sister drown, and Billy was kidnapped. The night terrors appear to be the creatures' initial contact with their victims, establishing a supernatural link. This connection stays with people into adulthood, making them vulnerable to future attacks. The shared trauma creates a bond that allows the creatures to track and eventually abduct them.

Foreshadowing: As children, all the main characters experienced night terrors that their families dismissed as nightmares, but the creatures were actually reaching out to them.

At the end of the movie, Julia is committed to Dr. Booth's mental institution after her erratic behavior and assault on tunnel workers. While institutionalized, she is attacked by the creatures and pulled into the dark dimension she previously saw in mirrors, this time from inside a closet. She screams for help, but Dr. Booth and an orderly cannot see or hear her. The doctor closes the closet door, and the creatures drag Julia away into their realm. The ending implies she has been abducted, just like Billy was in 1983, with no hope of escape.

Foreshadowing: Julia's journey consistently mirrors Billy's, they both experienced night terrors, received warnings about the dark, saw the creatures, and were ultimately taken.

Light is the only defense against the creatures. Sarah explicitly states that light is what keeps them away, and the creatures emerge only in darkness. This is why Billy filled his childhood room with batteries, he needed constant light to ward them off. The creatures cannot cross into illuminated spaces, which is why Julia and others seek out light whenever darkness approaches. The creatures' vulnerability to light explains why they emerge from closets, shadows, and dark subway tunnels, always waiting for the lights to fail.

Foreshadowing: The opening scene in 1983 shows Billy afraid of the dark and his mother checking his closet, establishing the creatures' aversion to light from the start.

The long black needle emerges from the body of someone the creatures are targeting. When Julia discovers the mark on her forehead and pulls out the needle, it represents a final warning, her abduction is imminent. The needle appears to be some kind of anchor or tether connecting the victim to the creatures' dimension. Removing it does not save Julia; she is still taken later in the film. This suggests the needle is a symbolic rather than physical barrier, marking her as chosen for abduction.

Terry stabbed her father because during a night terror episode, she believed he was a demon. Her night terrors began after witnessing her sister drown in a lake, and during one episode, she vanished from her bedroom and ended up in the dog house. When her father reached in to pull her out, Terry was convinced he was not human but a demon in disguise. She attacked him with a kitchen knife, stabbing him in the eye. This traumatic event demonstrates how the night terrors cause victims to perceive ordinary people as threats, blurring the line between reality and the creatures' influence.

The bathroom mirror opened into a parallel dimension where the creatures live. When Julia investigated the running shower, black fluid erupted from the sink drain, and the mirror became a portal to the creatures' realm. This suggests the creatures can manifest through any reflective or dark surface connected to their dimension. Paul found Julia alone, and she could not explain how the creatures appeared, this was the first time she saw them in her adult life, confirming Billy's warnings were real.

Foreshadowing: The creatures have always emerged from dark spaces like closets, so a mirror opening to their dimension follows their established method of invasion.

Terry and Sam are abducted by the creatures. After studying Billy's diary and sharing their own night terror histories with Julia, the creatures come for them at their apartment. They represent two of Julia's allies who believed her warnings about the dark creatures. Their abduction leaves Julia alone to face the threat, increasing the isolation and urgency of her situation. Like Billy and ultimately Julia, they are taken into the dark dimension from which no one returns.

Billy kept batteries as a desperate attempt to ward off the creatures. Since light is the only defense against them, batteries powered flashlights and lights to keep his room illuminated. The discovery of the full drawer reveals Billy spent his life living in fear, constantly preparing for the creatures' return. This explains why he was deathly afraid of the dark as an adult and why he warned Julia to stay in the light. His entire adult life was defined by trying to prevent a reappearance of the beings that took him in 1983.

Julia's father's suicide triggered her night terrors, which established her connection to the creatures. She witnessed him kill himself, and this traumatic event caused her to experience severe night terrors as a child. The trauma made her vulnerable to the creatures, just as Terry's sister drowning and Billy's abduction made them vulnerable. The creatures appear to be drawn to people whose traumatic night terrors created an opening for them. Julia's childhood trauma is the reason she was targeted, and the creatures eventually come for her as they came for the others.
